DB<2> c 2586
main::(blah.pl:2586):
2586:     my $found_cycles = 0;
2587:     SOME_LABEL:
[download]

Note the colon after the label's line number. The debugger uses this hint to say this line is breakable. The label belongs to the statement after this:

2586:     my $found_cycles = 0;
2587      SOME_LABEL:
2588:     while (<INFILE>)
2589      {
[download]

In fact, if I just list the lines, the colons are correct. Seems to be when stopping with a continue or break they aren't.

But I'm surprised the label is displayed for the previous statement, and not the next. If I break on the while, I get this:

  DB<3> c 2588
main::(blah.pl:2588):
2588:     while (<INFILE>)
2589:     {
[download]

Note that the opening brace is considered part of this statement (ignoring the colon, as this line isn't breakable).

Comments?
